  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.   
Eyes Redness. Pain.  Wear safety spectacles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Store and dispose of according to local regulations.

PACKAGING
 
MANGANESE SULPHATE MONOHYDRATE ICSC: 0290
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
PINK HYGROSCOPIC CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces sulfur oxides and manganese oxides. This generates toxic hazard. 

Formula: MnSO4.H2O
Molecular mass: 169.0
Relative density (water = 1): 2.95
Solubility in water, g/100ml: 76.2 (freely soluble)
Melting point: 400-450°C  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
The substance may have effects on the central nervous system. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Mn, respirable fraction): 0.02 mg/m3, as TWA; (as Mn, inhalable fraction): 0.1 mg/m3, as TWA; A4 (not classifiable as a human carcinogen).
EU-OEL: (as Mn, respirable fraction): 0.05 mg/m3 as TWA; (as Mn, inhalable fraction): 0.2 mg/m3 as TWA.
MAK: (as Mn, respirable fraction): 0.02 mg/m3; (as Mn, inhalable fraction): 0.2 mg/m3; peak limitation category: II(8); pregnancy risk group: C 

ENVIRONMENT
The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
The apparent melting point caused by loss of crystal water is given.
